Gravity and force

Launch escape thrust of a Soyuz rocket

This is the force produced by the Soyuz rocket's launch escape system to rapidly move the crew capsule away in an emergency.

How big is it?

4 MN of force

Force · approximate
Typical recorded range: 3.8 MN to 4.2 MN.

Scale illustration of Launch escape thrust of a Soyuz rocket, calibrated to its force measurement.
The marked force represents 4 MN.

A little perspective

Falcon 9 liftoff thrust is about 1.9 times larger on this measurement.

Falcon 9 liftoff thrust: Falcon 9 liftoff thrust is the total force produced by the Falcon 9 rocket's engines to lift it off the launch pad.

Why this measurement?

Why we use 4 MN

For comparison, this page uses force. This is labelled approximate; the central value is useful for comparison, while real values or measurement solutions can vary. The recorded range is 3.8 MN to 4.2 MN.
